For the large part and for C code, I would say that the difference is 
small in most cases for x86-64.  I see a small lead in floating point 
performance using the Studio compiler, and a small lead with integer 
performance using GCC.  However, either one might come out in the lead 
for any given test case.

When it comes to SPARC code, the Studio compiler is clearly in the
